Laser Cutter Won't Start? Here's Why

After long-term use or disuse, some users will find that the laser cutting machine has abnormal phenomena when starting, so what are the reasons for the abnormal startup of the laser cutting machine? How to solve these problems?

Common reasons for abnormal startup of laser cutting machine

Power supply problem

The power supply is the basis for the normal startup of the laser cutting machine. Unstable power supply or voltage fluctuation may cause the equipment to fail to start or start. In addition, loose power wiring or loose power plug may also cause insufficient power supply, thus affecting the normal operation of the laser cutting machine.

Laser tube failure

One of the core components of the laser cutting machine is the laser tube. If the laser tube fails, such as aging of the laser tube, gas leakage or insufficient coolant, it will cause the laser output power to be unstable, or even unable to emit a laser beam, which will affect the startup of the equipment.

Optical path system pollution

The optical path system of the laser cutting machine needs to be kept clean, especially optical components such as reflectors and lenses. If too much dust or dirt accumulates in the optical path system, the transmission efficiency of the laser beam will decrease, and in severe cases, it will cause abnormal startup of the equipment.

Electrical system failure

The electrical control system of the laser cutting machine is responsible for coordinating the operation of various components. If the control system or electrical components are aging or have poor contact, the machine may not receive the correct start signal, resulting in abnormal startup.

Gas source or cooling system problem

The laser cutting machine requires a stable gas supply (such as oxygen, nitrogen, etc.) and cooling system support during operation. If the gas supply is insufficient or the coolant flow is unstable, the equipment may not start or run normally.

Solutions to abnormal startup of the laser cutting machine

Check the power supply and electrical connections

Make sure the power supply voltage of the laser cutting machine is stable, and check whether the power cord, plug and switch are normal. Check the electrical connections regularly to ensure that there is no looseness or short circuit. If there is an unstable power supply problem, it is recommended to use a voltage stabilizer or UPS power supply to ensure the normal startup of the equipment.

Regular maintenance of the laser tube

The laser tube is the core component that affects the startup and operation of the cutting machine. Regularly check the service life of the laser tube, replenish the coolant in time and clean the laser tube. For laser tubes that have aged, replace them with new ones according to the usage.

Clean the optical path system

Regularly check and clean the optical path system of the laser cutting machine, especially the mirror, lens and reflector, to prevent dust and dirt from affecting the transmission efficiency of the laser beam. You can use a special optical cleaning tool to gently wipe to ensure the cleanliness of the optical path system and the quality of the beam.

Check the gas source and cooling system

Ensure that the gas source of the laser cutting machine is working properly and replace the gas source filter regularly. Check the water temperature and flow of the cooling system, and replace the coolant in time to prevent the laser tube from overheating due to high temperature or insufficient flow, which affects the startup.

Regular software and hardware updates

The control system of the laser cutting machine may fail due to long-term non-updates, resulting in abnormal startup. Therefore, the operating system and software of the equipment should be checked and updated regularly to ensure stable system operation and resolve possible program errors.

As a high-precision device, the abnormal startup of the laser cutting machine may be caused by multiple factors. Through regular maintenance inspections, reasonable operations and timely troubleshooting, the problem of being unable to start the equipment can be effectively solved, the service life of the equipment can be extended, and production efficiency can be improved.
